submitting applications for licensing construction of wastewater collection and transmission systems in Broward County, Florida. It is an interpretation of, and not meant to replace, the minimal sound principles of 1,2Engineering, or the provisions of the 3Florida Administrative Code, Chapter 62-604, or the

4Broward County Code of Ordinances, Chapter 27.

State of Florida Local Program Delegation

The State of Florida Department of Environmental Protection (DEP) has delegated Broward County Environmental Protection Department (EPD), Water Resources Division (WRD), the local wastewater collection system licensing program. By submitting the appropriate DEP forms to EPD, you will also be fulfilling the requirements for the DEP Wastewater Collection/Transmission System permits. Construction Projects Which Require Wastewater Licensing

Each non-contiguous project requires a separate application and fee pursuant to 3Florida Administrative Code, Rule 62-4.050(4)(s).

Pursuant to 4Chapter 27, "prior to any person constructing, extending, or altering a gravity sanitary sewer, sanitary force main, or pump station, that person shall obtain a county license". This section of the Broward County Code applies to the following:

1. Construction of a new gravity sewer, force main, and/or reclaimed lines. 2. Construction of a new sanitary sewer pumping station. 3. Increase in capacity of an existing gravity sewer and/or force main. 4. Increase in capacity of an existing pump station. 5. Relocation of an existing pump station or any portion of the sanitary system. 6. Construction and development activity resulting in increased flow to the waste

water treatment plant. Construction Projects Which May NOT Require Wastewater Licensing

Any other maintenance to a collection/transmission system may be exempt from licensing requirements. Some types of modifications require no changes in any existing permits and no evaluation by the EPD Water Resources Division. Examples of these include:

1. Construction of laterals from a single establishment. 2. Rehabilitation of an existing collection/transmission system as originally

designed. 3. Activities associated with routine maintenance.

Minimum design information requirements

1) Gravity sewers using anything less than standard slopes or larger than 8" pipe requires a site analysis study detailing the non-standard requirements for staff consideration.

2) A sewage pump station requires design calculations which consider

superimposed pump curves, floatation calcs, and pipe sizes.

3) Any new project generating .01 MGD or larger flows into existing sanitary systems will require a study proving adequate system capacities through to the WWPT.

4) Existing sewage pump stations which have been in service for more than five

years, or are approaching built-out condition, will require an operational assessment prior to new construction licensing.

5) All affected sewage pump stations shall be posted with a notice indicating

the name and phone number of an emergency contact and other contact information as applicable for over flow clean up of the facility. This notice shall be displayed with the minimum of 1" high block letters on the outside of the electrical panel, fence enclosure, or other conspicuous location.

This is to include the following statement:

ATO REPORT POLLUTION, CALL BROWARD COUNTY EPD" Should the system be owned and maintained by a private entity, an addendum must

be noted on the applications, prepared and signed/sealed by the Engineer of Record, and signed by the applicant. This addendum must address the agreement with the receiving public utility, and future maintenance of the system.

Certification of Completion of Construction Procedure Upon completion of construction, and prior to usage of the system, DEP and EPD

require: G DEP Form #62-604.300(8)(b), Request for Approval to Place a Domestic

Wastewater Collection/Transmission System Into Operation. Any deviation to the original construction design must be noted under item (4) Page 3 of 3.

G Broward County EPD Page 4 Addendum to the above form.

Gravity Sewer:

G Information submitted should include, but is not limited to: lamping reports, leakage tests, etc...

Lift Station

G Information submitted should include, but is not limited to: equipment manuals, pressure tests, lift station start-up reports, signage photo, copy of contracts, etc...

G One full set of "as-built" record drawings submitted for approval, signed and sealed

by the Engineer of Record. EPD may inspect projects prior to certification for compliance to standards. Therefore, these documents should be submitted prior to covering trenches. However, if paving of roads, pouring of sidewalks, planting and landscaping, etc., are done prior to EPD as-built approval, it shall not relieve the licensee from the responsibility for making any corrections to the sanitary sewer system as may be required by the county.

G The current EPD Arecord drawing @ review fee of $100.00, made payable to the

Broward County Board of County Commissioners. This fee is pursuant to 4Broward County Code of Ordinances, Chapter 27.

Once the system is approved for partial or final certification, a letter will be issued to

the Engineer of Record, along with copies to the appropriate officials. A Certificate of Occupancy shall not be issued by the building permit authority unless the project Aas-builts@ have been approved by EPD, and approval letter issued. To do so is a violation of 3State and 4County Rules and Regulations, and may be subject to enforcement action resulting in civil penalties and/or fines to all parties. As-built Deviations

In staff's review of as-built drawings, a deviation from design slopes of +/- 10% shall be considered. In addition, a tolerance of +/- 3/8" (.03') may be considered in manhole invert elevations where the slope deviation exceeds +/- 10%. Note that when this calculation is used, the resulting slope must be equal to or greater than the design slope. No further deviations from design slopes, regardless how slight, shall be considered.

Peaking Factors The appropriate peaking factor must be used to size all sewer systems. 1Chapter

23 of the 10-State Standards serves as a good reference in determining this factor. Design of Sanitary Sewer System Standards Slopes:

Gravity sewers shall be designed at slopes not less than the minimum recommended by the 1"Recommended Standards for Sewage Works," 1997 edition. Systems utilizing larger than 8" pipe require the following to be considered: G Design calculations proving that the project flow generated requires the

larger size pipe. G Plans must show existing pipe to be of equal or larger pipe.

Following is the slope chart referenced:

Minimum Slope in Feet Sewer Size Per 100 Feet (m/100 m)

8 inch (20 cm) 0.40 9 inch (23 cm) 0.33 10 inch (25 cm) 0.28 12 inch (30 cm) 0.22 14 inch (36 cm) 0.17 15 inch (38 cm) 0.15 16 inch (41 cm) 0.14 18 inch (46 cm) 0.12 21 inch (53 cm) 0.10 24 inch (61 cm) 0.08 27 inch (69 cm) 0.067 30 inch (76 cm) 0.058 36 inch (91 cm) 0.046

Slopes greater than these are preferable.

The following must be designed by these minimal standards:

G The upper 400 lineal feet of any project. G If drop manholes and/or excessive elevation drops within the manhole are

utilized for the common trunk line, the entirety of the project. (This excludes the feeder systems which flow into a trunk line system.)

G Any specific site which, by staff review, does not require lesser slopes. These requirements may be waived if site-specific conditions show them to be

unattainable. A DEP Individual Permit will then be required.

9 of 15

For the remaining slopes, the following requirements for velocity must be met. Velocity:

Pursuant to 4Chapter 27, "gravity sewer design shall provide a minimum flow velocity of two (2) feet per second when the pipe is flowing full or half full". This velocity shall be computed based upon the Manning equation and a minimum n=0.012 (for PVC pipe). The design engineer may select another appropriate n factor, provided that adequate technical justification is submitted to EPD staff for approval. In no case shall an n value less than 0.012 be selected. The following table shows the slopes calculated in accordance with the previous stipulations: Pipe Size VCP/DIP (n=0.013) PVC (n=0.012)

8" 0.33% 0.28% 10" 0.25% 0.21% 12" 0.20% 0.17% 15" 0.15% 0.12% 18" 0.11% 0.10% 21" 0.09% 0.08% 24" 0.08% 0.07%

Design of Sewage Pumping Stations:

Information is to be provided on each pump station serving the project. Each station shall be submitted on a separate application. A set of engineering design calculations for the stations shall be submitted. This should include an analysis of the flow generated by the project, the hydraulics of the system, an analysis of the buoyancy of the station, and a pump/system curve. Pump station information submittal shall be in conformance with 1Chapter 10 of the 10-State Standards. Pump station design shall be in conformance with FAC 62-604, and 1Chapter 30 of the 10-State Standards. Design of Force Main:

Force main velocities at design average flow must attain a velocity of 2 feet per second. An automatic air relief valve shall be placed at high points in the force main to prevent air locking. The force main and fittings including reaction blocking shall be designed to withstand normal pressure and water hammer (surges). Friction losses through force mains may be determined using the Hazen-Williams formula, or other acceptable methods.

Force mains connected to gravity sewer systems shall enter the receiving manhole at not more than 2 feet above the flow line. The force main effluent shall be directed at the manhole outlet.

POTABLE WATER-SANITARY SEWER-Reclaimed WATER SEPARATION NOTES

The following statements must be included on all plans for sewage

collection/transmission systems and/or reclaimed water mains to meet the minimum requirements of the Florida Department of Environmental Protection (FAC Rule 62-555.314) and the Broward County Department of Planning and Environmental Protection. 1) VERTICAL CROSSINGS

Sanitary sewer systems and/or reclaimed water mains shall cross under potable water mains whenever physically possible. Sanitary sewer systems and/or reclaimed water mains crossing below potable water mains shall be laid to provide a preferred vertical separation distance of 12 inches (minimum 6" for gravity/reclaimed main) between the invert of the potable water main and the crown of the lower pipe.

2) HORIZONTAL SEPARATIONS

Wherever it is physically possible:

Sanitary sewer systems require a preferred 10-foot horizontal separation distance (minimum 6-foot) outside to outside of pipe between any potable water main parallel installations.

Reclaimed water mains require a minimum of a 3 foot outside to outside of pipe horizontal separation distance between any potable water main and/or a sanitary sewer system parallel installations. Wherever either are not physically possible, then the potable water main shall be laid at the maximum physical horizontal separation distance possible, and either laid: A) in a separate trench; B) on an undisturbed earth shelf; and conforming to the minimum Vertical Crossings in paragraph 1).

3) CONFLICTS

Wherever it is not possible to maintain the minimum standards in 1) and 2), then all piping material shall be ductile iron pipe (DIP). All DIP shall be class 50 or higher. Adequate protective measures against corrosion shall be used as determined by the design and site conditions. Additionally, the potable water main shall a full joint centered on the conflict and mechanically restrained. An absolute minimum vertical separation distance of 6 inches shall be provided between the invert of the upper pipe and the crown of the lower pipe.
